摘　　要：提出在特殊地形地质路段采用锚杆扩大基础的支护设计理念,针对重力式挡墙介绍锚杆扩大基础的结构设计方法与稳定性分析步骤。相对于常规的衡重式或重力式连体基础,锚杆扩大基础在使用性能与工程造价上均占有明显的优势,作为地形地质复杂山区公路的特殊支挡结构具有良好的应用前景。This paper recommends the design concept of applying anchor bolt expanded foundation retaining structure in special geography and geology road segment. Targeting at gravity type retaining wall, it introduces structural design method for anchor bolt expanded foundation and stability analysis steps. Comparing routine balance weight or gravity type connected foundation, the anchor bolt expanded foundation has better advantages in performance and project cost, it has better application prospect as special retaining structure in complicated geography and geology mountainous area roads.
